Abstract
An experimental study on 34 healthy male volunteers demonstrated that a therapeutic dose of diazepam (15 mg PO) influenced the reproduction of a conditioned emotional response (skin conductance activity) on subsequent test days. This effect depended upon the pharmacological state present at acquisition, and was in accordance with a drug-dissociation interpretation of diazepam's amnesic effect. The results are interpreted as an example of diazepam state-dependency effects upon development of behavioral tolerance to stress. The clinical consequence of the results indicates that patients under diazepam medication will to a certain degree be deprived of the ability to develop appropriate coping strategies. It is concluded that combining psychotherapy with diazepam treatment may have the opposite effects to those intended.
